i or metal bed ends. Among the objects of theinvention are: to provide a simple at` tachmeiit housing which can be made of a minimum amount of material and with few bending operations; to strengthen the housing itself by the application of the side rail; to utilize only the side rail in attaching it to the housing; to additionallystrengthen the housing by the attachment of the cross rail; and in General, .to produce the construction herein s iown and described.

Inthe accompanying drawing, Fig. 1 is a side elevation showing a corner lockernbodying this invention; Fig. 2 isa front view showing the side'rail in section; Fig is a plan view; Fig. 4 is a section taken on the line 4-4 of Fig. 3; Fig. 5 is a perspectivebf the housing; Fig. 6 shows .a blank from which thel housing is made; and Fig. 7 is a section of this supporting stud.

In carrying out this invention a housing 1 is formed up out of a single blank 2 of niaterial, as shown by Fig. 6. The blank and the housing comprises a central portion 3 with -perforations 4 through which fastening bolts 5 `are inserted fork securing the housing to a post 6. If the post is round, as shown in the drawings, this portion 3 is rounded to conform to the post, lbut if applied to a square lpost, the surface is made fiat. Atithe sides of the central portion are fold lines 7 and 8 lwhich make the `sides 9 and 10 respectively. Extending from 'the side 9 isan ear 11 which is folded upwardly on the inside'of the box or housing, and extending from the `other side 10 are ears 12 andj 13 the first of which is bent downwardly or withinthe box and the other one, 13, is bent outwardly. All ofI these ears are formed with perforationsV 14,

- and when the sides are folded'together the f ears `11 and 13 will `be disposed at right angles to .each other for the attachment` of a cross rail 15 by means ofwhich the housings are properly spaced apart butsecured toy"gether in pairs,` the cross bars being attached fby'means of rivets 16 inserted .therethrough and through lthe perforationsof the ears 11 d and13. y v

The ear 12 at'the top ofthe housing is Y preferably bent inwardl i at a slight distance r` as clearlyrshown in elow the upper edge o LFig. 2,and secured in they perforatioiiof this ear is a short stud l17the 1923. serial N. (930,756.

upper end of which is slightly bevelled and extends above the upper face Vof the ear.

In the outer side 9 `is a perforation 18 for receiving a shouldered stud or rivet 19 with its head 2O on the inside of the housing, the inner face 21 of the head being slightly bev'- elled to the shouldered portion 22. A side rail 23 which is adapted to engage the studs 19 and 17 is angular in form with a slot 24 inthe vertical web which fits over the shouldered portion 22 of the stud 19 and with. a perforation 25 in the horizontal web which engages over the bevelled end vof the stud 17 in the ear 12. The inclined face of thetstud 19 permits the lower edge of the vertical web of the side rail 23 to engage between the head f 20, the side 9, and the slot 24 to engage over the stud. In practice this slot24 Ais very slightly bevelled or widened at its outer yend sothat the stud 19 will be seated at the bottom ofthe slot. `The extremity ofthe rail is straight or square along the vertical web at this end 26, and the housing is formed with a corresponding flattened surface 27 which this end .abuts The horizontal web is cut off upon a line 2S so that this portion of the side rail will clear the curved central portion 3 of the housing blank, as shown more lclearly in Fig. 3. 1

` The extremities of the connectingcross bar 15y are preferably cut off at 29, as clearl shown in Fig. 2 in order that the verticalweh of the side rail `will be seated in the housing when the side rails are in position; the cross bar 15 connecting the lower portions of the sides by means of the ears 11 .and 13 to which it is riveted, `and the angle bar or side rail engaging the studs 19 and 17 over the to of the sides. It will also be seenthatwitli the side rail in `position a neat appearing housing willbe formed, as'the top of the side rail is Hush withY the upper .edge of the side 9 (see Fig. 2) with only a portionl of the stud 17 projecting above the horizontal web of the side rail. As the studs 17 and 19 are quite a distance apart, the side rail makes a rigid connection in the housing, and as the p studs are di'awn'up tightly by the applicathe opposite side `9,

tion of the side rail, there is very little play or tendency to become loosened. Furthermore, the extremity 26 of the vertical ,web

bears firmly against the plane surface 27 provided 'for that purpose in the housing and holds the rail iirmly in the proper relation with respect to the'stud 19. blank and the rail are all accurately eut and formed with dies, the rails are interchangeable end for end with any others and ymay be fitted into any of the boxes or housings.

To disengage the rail from `thehousing it its upper edge at a height slightly above and spaced from the other side, and an angle bar side rail having a notch in one edge for engagement with the projection at the side of the housing and with the` otherweb ofthe angle bar flush with the upper edge oi" the said higherside and also engaging the said other side of the housing for binding the spaced sides together.

2. In a corner lock, a hollow housing having two sides spaced apart, and one formed with an inwardly turned ear at the top, a projection extending upwardlyY from the ear, and an angle bar engageable with the projection yand also having means engagingthe other side oit the housing, thus binding the two sides of the housing together.

3. In a corner lock, a housingr formed with opposite sides, oneioi` whichihas an innen projection, means for connectingfthe sides across the bottom, an angle bar, one 4webct which has a slot engageable with the projection, and an ear projecting inwardly from the top ot the other side for engaging the other web of the anglebar, the angle bar thus binding the housing sides together across the top. j

4. In a corner lock, a hollow housing having parallel spaced sides, `one formed witlr an inwardly'turned ear at the top below the level oi the other side, means projecting inwardly from the said other side and means projecting upwardly from saidear. and an angular side rail engageable with both of said means and binding the sides together.

9. In a corner lock, ahousing formed 'olf sheet material with spaced sides and a straight abutment surface in the angle formed in bending one of the sides, a headed projection extending inwardly from this side, an earturned inwardly from the top ofthe other side having an upward projection, and an angle L bar side Arail having a` slot to lit over the headed projection, a perforation to iit over the projection inthe car, and a con tact surface at the end to engage the sli-aight abutment surface in thehousing.`
